IMPROVEMENT IN MACHINE PQR FASTENING- SOLES.

The Schedule referred to in these Letters Patent and making part o the same.

To all whom it may concern :Be it known that I, CHARLES H. Hnmts, of Poughkeepsie, Dutchess county, and'State of New York. have invented certain new land useful Improvements inSole-fastening Machines 'and I' do hereby'declare that the following is a full description of the same: f

The nature ot' my invention consists, in combination with the' pcrforated'clamp, of a movable pin or pointcr-faced nail-driver'platc, furthe purpose of fitting into the perforatious or nail-holes in the clamp, to force the nails into the sole of the shoe; but, to'describe my invention more particularly, I 'will refer to lche accompanying drawing forming a part of this specilication, the same letters of reference, wherever-.they occur, referring to like parts.

Figure 1 is a front. elevation ot the machine.

' Figure 2is a vertical cut section of the samcthrough the line a; x, iig. 1. `l

Figure 3 is a plan view'of the machine, showing the last-holder slid out from under the nail-driver and clamp.

Figure 4 is a cut section of the machine through the line x2 x2, fig; 1.

Letter A represents the frame or sides of the nia-,-

chine, which may he .made of iron or other suitable material.

At about half-way the height ot' the frame is secured a table, B.. Upon this table is adj usted, in suitable guide-ways, a last-holder sliding plate, C, having on its upper side, atfone cud, a center pin, D, and at the other or opposite end an adjustable toe-restor prop, E, which, by means of a set-screw, F, may be adjusted upon the plate C out or in, so as to fit the diiierent sizes" of lasts .R to .be operated on.

For the purpose of holding the shoe iirml y ou the last during thebperation of nailing the sole on,'a clamping-plate, G, haviugits ends iittinginto guideways H, on the inner side of the frame C, is forced Ydown upon the'face of the sole by means of afootlever, I, acting through connecting-rods J ,attached to the ends of the clamping-plate.

with which the sole is to be fastened ou the shoe.-

The object of this is to guide the nail, by holding it rmly ina vertical position while being driven into the sole, and thus secure acertain and uniform pene-4 tration of the nail. To accomplish this object, a seriesV of pins, L, of corresponding size with the holes in the clamp, and arrangement oi' them, aresecured into ther lower faceot a movable nail-driver plate, M, having its ends working in the guide-Ways H, the same as the ends of the clampiug-plate. The object of this is to insure at all times, and certainly, the'pins L, entering the holes K, todrive the nail or screw-pointed fastener into the sole, to secul'e it to theshoe.

To operate the nail-driver plate a rod, N, is solidlyr secured to the upper side ot the nail-driver, andextends up through a hole in the cross-bar ofthe frame C far enough to admit ot' a piu in its end engaging into a grooved cam-lever, P, secured in suitable bearings, S, attached to the cross-bar of the fra-me O. 1t wilhth'us be apparent that, by means of thehaudle ot' the lever P, the operator ou the machine can readily exert power enough to drive home, at one operation,

the whole set ot' nails that have been previously inserted into the guide-holes K, to secure the sole to the upper leather of the shoe. v

Having now described my invent-ion, I will proceed to set forth what I claim and desire to secure by Letd 1ers Patentot' the United States.

l' claiml A The combination of the nail-driver plate M, having 'the pins L secured therein, for the purposes set forth,

with the perforated clamping-plate G, substautiallyas described and for the purposes set forth.

Witnesses :A C. H. HELMS.
